CAR-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 285,173, datedSeptember 18, 1883.

Application filed March 1, 1883. (No model.)

To all whom it may concern Be it known that I, ISAAC WV. STEMEN, of

Elida, in the county of Allen and State of Ohio, have invented a new andImproved Railroad-Signal, of which the following is a full, clear, andexact description.

This invention consists of a revolving signal of targets by day andlamps by night, set on the top of the caboose or other hind car, andgeared by belts and pulleys with one of the axles of the car-truck, sothat the direction of their rotation will show which way the train isrunning, and their velocity willindi cate the speed of the train, andbeing at rest will show that the train is standing, all ashereinafterfully described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a side elevation of a freight-car with my improved signalapplied, and Fig. 2 is an end elevation of the reelon which the signalsare revolved.

I arrange a short shaft, a, in a suitable bearing-frame, b, on the topof the car 0, to carry target-signals d or lamps e on reel-arms f, to

I be revolved by suitable gearing connecting the shaft with one of thetruck-axles so that the signals will show to the train-men behindwhether the train is in motion or not, also which way and how fast it isrunning, the said shaft a being arranged lengthwise of the car, so thatthe reel-arms will swing crosswise, and the gearing consisting in thiscase of pulleys and belts; but cog-wheels and shafts may be employed,

if preferred. I use two belts, hand i, andthc requisite pulleys forreducing the speed of the reel, so that the signals may revolve, say,ten revolutions per minute for a speed of fifteen miles of the car perhour; and in order that the belt h will not be affected by rise and fallof the car on the springs, I train it horizontally for a short distancefrom the pulley on the car-axle. and then run it over guide-pulleys j tothe reducing-pulley 70, mounted on the side or top of the car, near thetop, from which the belt 03 runs to the shaft a.

iThe lanterns are suspended by hooks m from pivots a of the arms f, sothat they will swing upright, and the hooks are connected to thetargets, so that they swing over the lanterns. I do not limit myself toany particular con trivance of the drivinggear, for that maybe varied atwill.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is

In a car-signal, a car carrying on its top a frame, 5, the shaft to,supportedby said frame and bearing the reel-arms f, the targetsignalspivoted at the ends of these arms, and the signal-lights suspended fromand serving to maintain the targets in. vertical position by theirweight, all combined with mechanism for operating the signal connectedwith one of the truck-axles of the car, substantially as described.
